Merge pull request #271 from tendermint/develop

Merge develop into master:
- to tag and release v0.15.0 on master
- to delete develop after that

Release v0.14.1 (#244)

* add contribution guidelines

- minimal changes to ensure proto3 compat. for unsigned ints (int,
int32, int64)

* Add changes to decode ints, too

* Delete outdated tests (covered by new table driven test)

* Add overflow checks for int & int32

* prep release: update changelog

* Make amino build on 32bit architectures (#242)

* fix int overflows that happen on 32bit systems
 - explicitly type constant in time encoding
 - use math.MaxInt32 in int tests to seed the fuzzer

* Add --concrete-name option to aminoscan

Release 0.14.0 (#240)

* minimal changes to ensure proto3 compat. for unsigned ints (int,
int32, int64)
* Add changes to decode ints, too

* Fix example that contains an int

* Add changelog entry

* Delete outdated tests (covered by new table driven test)

* Add overflow checks for int & int32

* unum -> u64

* prep release: update changelog

Merge pull request #236 from tendermint/fix_renaming

Fix renaming of UnmarshalBinary

Update changelog to include other merged PRs

Release/v0.12.0 (#216)

* DecodeInt{8, 16} negative limit checks + tests (#125)

Updates #120

Also adds a test for Byteslice encoding and decoding
roundtripping and part slicing then rejoining.

* fix circleci2.0

* some metalinter issues

* skip over default values when encoding time (#178)

* do not encode empty structs, unless `amino:"write_empty"` is set (#179)

* skip over empty structs by default

* slightly more info on panics

* Fix zero time decoding (#190)

- fix decoding of skipped fields in time, or completely skipped time 
- necessary because sec=0 and ns=0 do not result in time.Time{} and vice versa

* Prepare release 0.11.0 (#193)

* Fix time decoding & encoding of arrays and structs

- top-level entry functions called with BinFieldNum:1 to properly encode e.g. arrays of structs (see non-time related test)
- add defaultValue method, different from #196 it deals with multiply nested pointers

* Removed dependency on tmlibs/common

* Always write empty if struct field is pointer

* add tests for #206

- test for pointers to empty struct and nil pointer

* fix proto3 compatibility for empty structs

* Add EmptyStruct to fuzz tests

* Revert "fix proto3 compatibility for empty structs"

* Do not allow encoding of nil struct pointers in a slice/array

* By default, 0-length list elements are decoded as nil
